MACHINE FOR AND METHOD OF HEEL-SEAT FITTING.

Application filed September 23, 1919. Serial No. 325,760.

This invention relates to the manufacture of shoes and is illustrated herein with reference to the heel-seat fitting operation performed preparatory to the attachment of wood heels to shoes.

Wood heels are commonly formed with a. cupped orconcave attaching surface, the periphery of which directly engages the upper of the finished shoe so that the margin of the sole does not show between the heel and the upper. To permit this and to provide a secure anchorage for the wood heel, it is the practice to reduce the heel-seat of the sole by removing surplus material from the peripheral portion thereof, the heel-seat being at the same time beveled so as to conform to the cupped attaching surface of the wood heel. A pair of shoulders are commonly formed also at the heel-breast line to engage the breast of the heel.

It is essential to good shoemaking that the heel-seat fitting operation, which is sometimes spoken; of as cutting on the heel. should be performed with a considerable degree of accuracy. If insufficient stock is removed from the sole, it is impossible to bring the edge of the heel into close contact with the shoe upper and a neat appearance cannot be obtained. If too much stock is removed, a secure anchorage for the heel cannot be obtained and the shoe is weakened.

i placed too far forward, thereby spoiling the to locate the heel-breast line.

lines of the shoe, or there will be a gap between the breast of the heel and the sole, and this, of course, cannot be permitted.

Prior to the present invention the heelseat fitting operation has usually been performed by hand. The workmarrtakes the ."wood' heel which is to be attached to the breast receiving cuts approximately at right will cut a good many of them out of place..

The trimming operation, moreover, that is to say the beveling and removal of the surplus stock from the periphery of the heelseat, as done by hand, is hard work and is consequently expensive. Moreover, since a wood heel cannot be attached to a shoe if insufi'icient stock is trimmed from the periphery of the heel-seat of the sole but can be attached, thoughnotas securely as it should be, if too much stock is removed, there is always a tendency on the part of the workmen to remove more stock than they should.

With these circumstances in view, it is an object of the present invention to provide an improved method of and machine for heel-seat fitting, which will make it possible even for inex 'erienced and unskilled workers to perfor the heel-seat fitting operation easily and expeditiously, and therefore at a smallexpense, and with assurance of accuracy.

In its method aspect the invention insures accurate control of the fitting operation by gaging the forward extent of the trimming operation-from a heel such as is to be attached to the particular shoe operated upon, located in a predetermined pos tion at a substantial distance from the heel-seat of the shoe. This method, which is particularly adaptable to machine operation, is disclosed herein with reference to a heel-seat fitting machine, which, as illustrated, constitutes a preferred embodiment of the invention in its machine as ect. This machine, in accordance with eatures of the invention, is provided with shoe-positioning means and a cutter arranged for relative movement to cause the cutter to trim surplus material from the peripheral ortion of the heel-seat of a shoe positioned y said means, the extent of the relative movement being controlled .or gaged through suitable connections from a heel located at a predeterminedposition a substantial distance from the heelseatof the shoe. As illustrated, theheel -which thus serves to control the extent of the trimming operation is placed between a pair of gage members which are mounted for relative movement so that one of them may engage the rear and the other the breast of the heel, the position of one of these members relatively to other parts of the machine controlling the extent of the trimming op eration.

Since some wood heels are made as rights and lefts, being longer upon the outer side than upon the inner side, provision is made in the illustrated machine for controlling the trimming cut accordingly; that is to say, if such a heel is to be attached to the shoe and is accordingly used to control the heelseat fitting operation, the forward extent of the trimming upon the two sides of the heel.-

seat will be unsymmetrical to the same extent that the heel itself is unsymmetrical, extending further forward on the outer edge than on the inner edge of the sole of the shoe.

In accordance with other features of the invention, the herein disclosed machine is provided with shoe-positioning means, including a crease plate arranged to enter the rand crease of a shoe, and a chop knife, the shoe-positioning means and the knife being arranged to permit relative movement of the knife and the shoe operated upon peripherally of the heel-seat of the sole of the shoe to cause the knife to trim surplus material from the heel-seat of the sole. As the path of movement of the knife is inclined relatively to the surface of the sole, the heel-seat is at the same time beveled and rendered convex to correspond with the concave attaching surface'of the sole. The knife of the illustrated machine, in accordance with a further feature of the invention, is provided with a plurality of angularly related cutting edges so that the surplus material is removed in the form of a succession of chips, the heel-breast cuts being made by edges of the knife positioned approximately at right angles to the edge of the sole.

While the invention has been disclosed herein particularly with reference to the heel-seat fitting operation, it should be understood that this disclosure is illustrativeand that the invention in its machine aspect is not limited toamachine for performing r this operation, since in various of its aspects the invention is useful inconnection with the performance of other operations.

With the above and other objects and-features in view, the invention will now be described in connection with the accompanying drawings and pointed out in the claims.

The removal of surplus material at the edge of the heel-seat of the sole of a shoe l mu is accomplished in the machine to be herein described by means of an oscillating chop knife 38 (Fig. 1) moving in a fixed path at an acute angle to the tread surface of the sole. The work" is mounted upon a supporting jack 5O movable in a horizontal plane upon the machine to present the various parts of the heel end of the shoe to the tool and to cause the removal, by successive cuts of the oscillating knife, of a horseshoe shaped section of surplus material extending from the heel-breast line rearwardly around the rear of the shoe and forward to the heel-breast line at the other side of the shoe. The trimming operation is controlled by means of a crease plate or guide 46 positioned adjacent to the knife to enter the rand crease of the shoe and a heel-measuring device 78 (Fig. 16) movable with the shoe and arranged to start and to terminate the operameans comprising an oscillatory shaft 6 (Fig. 1), having a. hand lever 8, for operating it, and a gear 10 (F ig, 17), which is arranged in mesh with a rack 12 on the under side of the table 4. An upright frame 14 is secured on said base in the rear of said table, the upper portion thereof being bifurcated (Fig. 2). .A main shaft 16 is journaled in said upright frame 14 and is constantly driven by a. pulley 18, and an auxiliary shaft 20 (Figure 1) is journaled in the base and driven from said main shaft by means of pulleys 22 and 24 and a belt 25. The shaft 16 is provided with an eccentric, 26, to which an eccentric rod 28 is connected and the opposite end of said rod is connected to an oscillatable knife carrying lever 30, which is mounted on-apivot 32, supported in a block 34, arranged to be vertically adjusted in a slot formed in the upper end of the frame by means of adjustingscrews 36.

The trimming or fitting operation is acv complished by successive cuts madev by a channelshaped, oscillating chop knife or cutter 38 acting to remove surplus material chip by chip from the edge of the sole from the heel-breast line rearwardly around the periphery. This knife or cutter is carried by the lever 30 which extends forwardly and obliquely downward from'its pivot and is provided with a rectangular-shaped projection 30 (Fig. 4) at its end, on which the channel-shaped knife 38 is mounted. As shown in Figs. 3 to 6, said knife is formed to provide three cutting edges, 38 38 and 38, arranged 'contiguously and at right angles to each other successively, the edges 38*, 38, being arranged at right angles to the intermediate edge 38*, at its opposite ends. Thus this cutter, turning'on an axis, is provided upon each side with radia-l cutting edges acting in planes tranverse to the pivotal axis of the cutter. The cutter is also provided with an outer cutting edge disposed lengthwise of this axis and traveling in a path between the paths of the side cutting edges so that the surplus stock is removed chip by chip. The shank portion of the knife is correspondingly. formed, so that its s de' and bottom portions form a. right an: gular groove in which the end portion of the projection 30 -is adapted to fit, the face at the end of said projection being at approximately right angles to the lever arm, so that the knife will be held on the lever in a right angular position relative thereto. Clamping plates 40 are bolted to opposite sides of the lever'arm, to clamp the sides of the knife against said projection 30 and said knife is provided with a threaded lug 38, adapted to receive an adjusting screw 42, the head of which is swiveled in a bracket 44 (Figs. 2

and 3), secured to the lever arm, so that said knife may be adjusted longitudinally. A

passes through a slot 43 in the sides of the knife and, when tightened, firmly clamps the knife in adjusted position. The sides and bottom of said knife are integral and their In order to support the edge of the sole and to assist in positioning the work with respect to the cutting path of the knife 38,

a crease plate or guide 46 having a tapered edge to enter the rand crease of the shoe, is mounted on a bracket 48, which is secured to the frame 14, and on which it is horizon tally adjustable. guide 46 is horizontal, and the arrangement is such that, whenthe lever 30 is oscillated. the knife will be reciprocated, or vibrated approximately longitudinally along a path oblique to the tread surface of the sole to cut through the periphery and form a bevel around the heel-seat. At the end of its down stroke, the knife edges will be positioned in the plane of the horizontal surface of the guide, and, at the points where the knife edges would engage said surface, a correspondingly shaped recess 46 is formed The upper surface, of the (see Fig. 12), so that the knife edges may be moved into the plane of the surface of the guide, without any actual engagement there with such as would tend to dull'the knife.

This recess is also formed to permit a slight shearing action at the finish of the stroke, so that the chip will be completely severed; The extreme edge of the guide is circular except at the portion in proximity to the intermediate portion of the recess which receives the bottom or intermediate portion of the knife edge, at which portion it is provided with a straight portion 46", which is in close proximity to, parallel to, and of the this end, a jack 50, having a flat base, is

movably supported, partly on thehorizontal surface of the table. 4, and partly on a guid- I ing plate 52 (Figs. 9 and 17), of oblong form, which is arranged in a recess in the table, so that its upper surface is flush with the surface thereof; A T-shaped tongue 50 Figs. 13 and 17 is formed on the bottom of thelbase of the jack 5 0, which is slidably engaged with a correspondingly shaped slot formed in the upper surface of the plate 52, so that the only relative movement permitted therebetween is a longitudinal sliding move-- ment. 'The plate 52 is provided on its under side with a stud 52 (Figs. 9 and 13), which is rotatably mounted in a recess or aperture formed in the table, and the ends of the plate 52 are curved on arcs having said stud as a center. Said stud 52 is located substantially nearer one end of the plate 52 than the other and the side of the recess in the table, in which the plate is located, is also curved about the center of the stud (Fig. 7). The rear end of the jack base is formed on a curved line which corresponds approximately to the outline of the heel end of a shoe, and a gear rack 50 (Fig. 8) is formed thereon, which extends from a point at one side about the rear of the base to a corresponding point at the other side.

A vertical shaft 54 (Fig. 17) is journaled in the rear end of the table 4 and is provided with a gear 56 at its upper end, which is arranged in mesh with the gear-rack 50 on the jack, and the lower end of said shaft is provided with a bevel gear 58, which is arranged in mesh with a" bevel gear 60, mounted on a sleeve 62, the latter being journaled in a depending portion 4 of the table and held from longitudinal movement therein. A shaft 64 is journaled in the machine base 2 and the sleeve 62 is splined on said shaft,

so that the table may be moved forwardly and rearwardly and a driving. connection maintained between the shaft 64 and the gear-rack 50 on the jack.

A bevel gear 66 is secured on the rear end of shaft 64 and arranged in mesh with a pair of bevel gears 68 and 70 (Figs. 14 and 15), which are mounted to rotate freely on the shaft 20, a clutch sleeve 72 being splined on the shaft 20 between said gears 68 and 70 and movable into driving engagement with either, to cause opposite rotation of shaft 64. *An' operating lever 74 for said sleeve 72 is pivoted on the machine base with its upper end arranged in engagement with a lever 76, the rear end of which is pivoted at 77 (Figs. 13 and 16) to the upright frame 14, said lever 76 having arms 76*, 76*,at its front end. A cross bar 78 is mounted on an adjusting screw 80 in the jack base in position to engage the arms 76,

7 6 as hereinafter explained.

Manually controlled means for operating the lever 76, are also provided, comprising a link 82 (Fig. 16), which is connected to said lever 76 and to a bell-crank lever 84, the latter being also connected by a link 86 to an operating lever 87 (Fig. 1).

Accurate control of the heel-seat fitting operation in the machine of the present invention is secured by the provision of a heelmeasuring device located upon and movable with the jack 50 and of connections between said measuring device and the operating parts of the machine to terminate the operation of the machine at points corresponding to the position of the heel-breast'line in the finished shoe. The measuring device comprises a fixed abutment 88 arranged to co-operate with the cross-bar? 8 to measure 6 a heel, said cross-bar being arranged to engage the clutch operating means as above suggested when, in the relative traversing movement ofthe shoe and the cutting knife, the knife operates at a position corresponding to the position of the heel-breast line.

Thisshou der 88 (Figs. 1, 13 and 16) is located on the base portion of the jack at its rear end,-and, before a heel (or one of a number of heels having the same base length) is attached to the shoe, the heel is placed on the base of the jack with its rear end against said shoulder, and then the bar 78 is adjusted so that its edge bears against the breast of the heel. The jack is provided with a form or extensiblelast 90, on which the shoe to be operated on is placed.

In placing the shoe on the last, the table is moved out from its rear position by means of the hand lever 8 and then is moved back so that the edge of the guide 46 engages the randecrease of the shoe. In starting the operation, the jack will be in a position side towards the front, as in Fig. 16, and the clutch sleeve 72 will be in a neutral position midway between the gears 68 70. The knife 38 will be rapidly vibrated, so that, when the shoe is moved back against the crease guide 46, the knife will remove a chip at the edge of the sole on a bevel, as indi-.

Assuming the jack is in the position of Fig. 16, the operator will then push the handle of lever 87 rearwardly, causing the lever 76 to be moved to the position shown in Fig. 7, this movement causing the clutch sleeve 72 to be thrown into engagement with gear 68, thereby causing rotation of gear 56 in'the direction indicated by the arrow thereon in Fig. 7. This rotation will first cause a sliding movement of the jack to the right, on the plate 52 as allowed by the tongue 50 through the engagement of the gear 56 with the side portion of the gear rack 50, so that the shoe will be moved past the knife, which will remove additional chips, as the shoe is fed. further to bevel the periphery of the heel-seat portion of the sole. As soon as the gear 56 engages the rounded portion of the gear rack 50, the jack 50 and the plate 52 ,will begin to swingtogether about the pivot should be. finished, one end of the bar 78 will engage the arm 7 6 of the lever 76, and move the same sufficiently to cause the clutch sleeve to be thrown out of engagement, so that the feeding movement is arrested. On account of the shape of the knife 38, or the provision of the side blades, a square shoulder will be formed at each end of the out, against which the heel breast will bear when in position on the shoe and the sole edge portion will be removed to permit close contact of the concave attaching surface of the heel with the'heel-seat of the sole and so that the periphery of the heel will seat on the shoe upper. j

, During the operation above described the shoe is held against thecrease plate or guide 46, the table being moved inward or outward, as it is turned, according to the configuration ofthe'shoe, the jack thus having universal movement in a horizontal plane, in so far as may be necessary to present the shoe in the ro er position for engagement with the kni e, in performing the heel-seat fitting operation.

The shoe may be held yieldingly in engagement with the crease guide 46 by means of the hand lever 8, or a weight 92 may be attached to' the rear end of the table by means of a cord or chain 94 passing over a pulley 96 (see Fig. 13), which will act automatically to hold the shoe against the guide with the desiredforce during the feeding movement of the jack. L

When the operation on one shoe is finished, the ,jack will be in the opposite position to that in which it was at the beginning of the operation, and when the next shoe is to be o erated on, the jack will be moved out, while in this last position, and the shoe which has been operated on will be removed and another placed on the jack. The jack w1ll' then be moved back and the above described operation repeated. When starting the operation with the jack in the opposite posltion to that of Fig. 16, the starting lever 86 will be pulled outward, so that, instead of having the gear 68 engaged by the clutch sleeve 7 2, as on the previous operation, the gear 70 will be engaged by said sleeve, causing opposite rotation of the gear 56, and, therefore, oppo: site movement of the jack. When the operation-is finished, the opposite end of the bar 78 will engage the arm 7 6 of the lever 76, moving the clutch sleeve to the neutral position, and stopping the feeding movement. WVhen the adjustment of the bar 78 is changed for a heel having a base of different length, the above described operation will be somewhat varied. It will be observed that vwhen the bar 78 moves the lever .76

from one extreme position to the neutral position, the bar will prevent the lever from being drawn back to such extreme position point.

into position and the cut would be made upv by. the starting lever 87, so that, to, start the feeding operation at all, the lever 87 must be moved so as to move the'lever 76 to the opposite extreme position. If, however, the bar 78 is moved away from the shoulder 88, to provide for a heel having a longer base than that for which the bar was previously adjusted, the jack being in the dotted line position of Fig. 7, or the position of Fig. 16, the starting lever would then be moved back to the position from which it was thrown by the bar 78, when the lever. 76 was last thrown to neutral position. The feeding operation would then be started, and almost immediately stopped at the point where the cut was to terminate; then the starting lever would be pulled in the opposite direction and the entire heel portion would be operated on, except the short portion already out. If, on the contrary, the succeeding heel had a shorter base than the one preceding, it would,

be necessary to operate the feed, before the I table was moved back far enough for the sole edge to be engaged by the knife, to an extent suflicient to enable the edge portion, to be beveled, to be engaged at an intermediate The table would then be moved back to one shoulder and then back to the other, as already described. 1

In some .cases the breast ed e or face of the heelisnot exactlyperpendicular to the central middle line of the heel, so that the sole would have to be beveled towards the shank farther on one side of the shoe than onthe other. Toprovide for such conditions, the cross bar 78 is connected to the screw 80 by a pivot bolt 81, as shown in Fig. 13, so that, when thebar 78 is adjusted against a heel w breast which is somewhat oblique to its center line, the bar may swing to a correspondingly oblique position, as shownin Fig. 7. lVhile the bar 78 is pressed firmly against the heel breast, it .cannot swing, so that, when either end engages the lever 7 6", it will move saids lever to neutral position, and this will take place earlier or later according to the position of the cross bar '7 8. As a result, the cut will be terminated at each side of the shoe, at points corresponding to the position of the heel breast when placed in position on the shoe.

Various other adjustments may be made to adapt the machine to diiferentconditions, for example, vertical adjustment of the heel and toe portions of the jack are sometimes necessary, to bring the shoe into thecorrect relation with the guide 46, the jack being provided with a well known means to permit such adjustment.

It will be understood that, while the illustrative embodiment, herein shown and described, is the best form of the invention of which I am at present aware, various changes may be made therein without departing from the spirit and scope of my invention.
